FILE PHOTO - (L-R) Zosia Mamet, Lena Dunham, Jemima Kirke and Allison Williams attend the HBO "Girls" Season 2 premiere at the NYU Skirball Center on January 9, 2013 in New York City. Dunham and the cast of "Girls" have lent their support to the “brave survivor” in the Stanford University sexual assault case in a video message calling for victims to be heard and supported.

A California judge's decision to give a former Stanford University swimmer a six-month jail sentence for sexually assaulting an unconscious woman has sparked outrage, but it has also reopened the often hushed-about discussion of sexual assault.

Collaborating with Now This News, the cast of "Girls" united to deliver a powerful message about the matter in hopes of creating a safer environment for survivors.

"I dedicate this to the brave survivor in the Stanford case who has given so much to change the conversation," Lena Dunham captioned the video on Twitter.

Joined by costars Allison Williams, Jemima Kirke and Zosia Mamet, the four explain the importance of facing the reality that sexual abuse happens more often that we'd like to admit, and also offer suggestions on how to be there for those who have experienced it.

"We may star on 'Girls' together but that doesn't mean we always agree," Kirke opens. "We sometimes vote for different candidates," Zosia adds, while Lena mentions, "We have very different views on appropriate undergarments."

Jemima explains, "But there is one issue on which we are in total agreement."

The women begin to discuss sexual assault and the alarming statistics given by the Center for Disease Control and Prevention, including that one in five women will be sexually assaulted in their lifetime, and one in four women will be sexually abused.

The cast concludes that you should offer support not because the survivor is someone's daughter or friend, but because "she is someone."
